screen i3.` The screen I3 is carried by a screen CID frame I4 that can be conveniently secured over the window opening, in spaced relation with the inside of the out-swinging sashes IIJ, by any suitable means. Each of the out-swinging sashes IG is arranged to be opened and closed by an operating mechanism I5 which projects beneath the screen frame I4 and connects with the bottom thereof. These operating mechanisms may be of any convenient form. As shown, the operating mechanism I5 comprises a crank I6 that controls a leverV (not shown) which is slidably connected to the bottom of the outswinging sashes It, as is well understood in the art. While the window operating `mechanism I5 is capable of opening and closing an associated out-swinging sash IIJ, it is necessary to also provide means which will lock the out-swinging sash in its closed position. This is provided for in the present instance by the locking means II which operates as will be hereinafter pointed out. The arrangement illustrated in Figure 2V of the drawings is similar to that described above, eX- cept that the window is provided with a single out-swinging sash I'I having a locking means IB mounted thereupon opposite its hinged side. The out-swinging sash I'i, like the cut-Swingin sashes ID, also has an operating mechanism I5 which is controlled by a crank I6. In this figure of the drawings the out-swinging sash I'I is shown as having a wire screen I9 supported thereover by a screen frame which can be mounted in any suitable manner upon the window casement.

Where a metal screen has been used in a casement window of the character contemplated by this invention, it has been necessary to either modify the screen structure or provide some special mechanism whereby the window locking means, such as the locking means II and I8 referred to above, could be operated without removing the screen from the window. This has been accomplished, in the past, by controlling the window locking means with an operating mechanism which extends beneath the screen frame in the same manner as does the Vsash operating mechanism I5, or by projecting a lock operating handle through an opening in the screen, or through the screen frame, as illustrated in United States Patent, Number 1,780,823, issued November 14, 1930, to Paul G. Johnson.

In accordance with the present invention, the sash locking means II and I8 have respectively operating handles 2I and 22 which extend out from the out-swinging sashes to a point closely adjacent or in actual engagement with the outsideof their respective covering screens I3 and I9. These operating handles 2l and 22 are also arranged so that they will move in an outward sash opening direction to unlock or release the sash locking means II and I8 when pressure is applied thereto from the inside of the screens I3 and I9. With a sash lock operating in this manner it is possible, by properly locating the wire mesh of the screens I3 and I9, to accomplish an unlocking of the out-swinging sashes with a .slight flexing of the` screens by pressure applied to the inside thereof and against the operating handles 2I and 22.

As shown in Figure l of the drawings, the lock operating handles 2I project upwardly and inwardly from the sash locking means I I and into close proximity with the screen I3 so that a lock releasing force may be applied thereto, immediately over their outer ends, through and by a flexframe.

Vframe 20.

ing of the screen I3. In order to indicate the points at which pressure should be applied to the screen I3 to release one or the other of the locking means II, the screen I3, as illustrated in Figure 3 of the drawings, is provided with two disc-like members 23. These disc-like members 23 are mounted against the inside of the screen I3 and are secured thereupon by means of a number of tabs 24 which project through and interlock with the wire mesh forming the screen. If desired these disc-like members 23 may be provided with a suitable legend, as for instance, Press here or Push to unlock. For the purpose of preventing wear on the screen by frequent contact with the operating handles 2I, similar disc-like members (not shown) may also be secured to the outside of the screen opposite the disc-like members 23. In the arrangement shown, the operating handles 2| are spaced so as to permit a flexing of the screen suicient to operate one of the handles 2I without causing an operation of the other handle. This makes possible an unlocking of either one of the sashes without an unlocking of the other sash.

Where the locking means is disposed substantially at the middle of the screen, no special precaution need be taken to insure against a breaking of the wire mesh of the screen as the result of al frequent flexing thereof. However, where the sash locking means I8 is located near one edge of the screen, as illustrated in Figure 2 of the drawings, some precaution should be .taken to insure against a too abrupt bending of the wire mesh where it is secured to the screen With this arrangement, it will be readilyseen that, should the screen I9` be flexed outwardly by pressure applied at the end of the operating handle22, the wire mesh will be subjected to an abrupt bending which in time would result in a breaking thereof where it engages the In order to overcome this difficulty, the frame 2l! is provided with a exible reinforcing member 25 which extends outwardly beneath the screen yand over the end of the operating handle 22.

As shown in Figures 4, 5 and 6 of the drawings, the iiexible reinforcing member 25 has a rounded shoulder portion 2S, over which the screen mesh is stretched. Because of its flexibility, the member 25 will yield with the screen when it is exed and thus prevent a sharp bending of the wire mesh where it engages the frame 20. The extending end of the flexible reinforcing member 25 has a button-like member 21 secured thereupon, against which pressure may be applied to move the operating handle 22 in a lock operating direction. The button-like member 21 is shown as extending through to the'inside of the screen I9 so that it serves to locate the point at which pressure should be applied to unlock the window.

In addition to providing against a too abrupt bending of the wire mesh forming the screen,

the fiexible reinforcing member 25, because of its rounded shoulder 26 and iiexible character, will also maintain the horizontal strands of the wire mesh disposed thereover in a taut condition and in their normal plane. As a further means to insure a tautness in the iiexing portion of the screen, there is shown a second flexible member 28 which is secured to the screen frame 20 directly opposite and in line with the flexible reinforcing member 25. The flexible member 28, like the fiexible reinforcing member 25, has a rounded shoulder, designated by the numeral 29.

which serves to prevent arsharp bending of the l'goor-,sce

screen wires at the frame. In the case of a screen arrangement, as rillustrated inliigure 1 of the drawings, itmay be ,desirable tof` provide. two ,iiexiblei members 28, one at eachsideof the screen frame and in` "ne with the operating handles 2l. ,.1 Y' in. While the individual'wiresforming the screens `isand` i9 are illustrated-in Figures. 1.,. 2 and l0 of the drawings as extending diagonally, `it should lbe `stated that this is not` the normal disposition of the wires; Aldiagonal showing'of thescreen forming wires is made, in the drawings, Vfor the purpose vof avoiding a confusion ofthe lines defining theiscreen with thev lines which define the other elements illustrated. `It is to. be understood, however, that thedisposition'of the wiresV of the mesh forming the screens is immaterial as screen'clothcut on `a bias canbev successfully used with this` invention.

From the foregoingit will be seen that the location ofthesash locking means beneath the i screenis` also immaterial. The lockingineans .operating mechanism l5; f *70 "1 isshown asso VVlocated with respectto the abut- :may be disposed centrally of thescreen, `asin Figure l of the` drawings, or adjacentoneside ofthe screen, as in Figure 2 of the drawings. In order that the locking `means may be controlled as contemplated by this invention, '.'it is desirable that the locking` means be constructed `so as to render an operation thereof possible byV pressure applied throughaexingpf the screen. Where the locking means'is carried. by the Voutswingingl sash, it is necessary that its operation be controlled by an outward window `opening pressure. 'While'this form of locking `means is vided with a means `which .will engage f the lock operating handle and impart an unlockingmovement thereto as the result of anA inward pull ex-l erted upon the screen adjacent the vend ofthe lock operating handle.` i u Reference is now made to the remaining iigures of the drawings wherein there are illustrated Vpreferred lock structuresand arrangements in which the operationof thev locking means `is controlled by an outward pressure exerted through and by an. outward exing of the screen.

In Figure 8 Vof the drawings, the out-swinging sash l'l is shownY as closed upon a" Casement 30 `which is set in a walldi. The easement 39 has a screen frame 2li secured upon 'the inside thereof `so as to. support Vthe screen I9 overfthe lock operating handle 22. The .locking means I8 is illustrated as comprising a support 32 having a horizontally disposed shaft 33, the end of which is bent outwardly toforrn 4a detent 34 at the end thereof.` The operating handle 22 is fixed upon the shaft 33 so `that when pressure is applied thereto the detent 34 will be 'forced down `andfout of engagement with an abutment 35, vcarriedby, the 'easement SEB; vto thus permit the out-swinging:sash` il `to be .freely opened by its In Figure lilof the drawingsthe detent 34 ment 35 that it will clear the latter-whenthe `operating handle 2E! is pressed outwardly. In order `to holdthe detent Stin itsznormal locking position, there is provided, about the `shaft 33, a

' screen I9.

atingv mechanism l5.

springBG which operatesto. bias the detent 34 into its upper orlocking position. This spring 35 also holds the operating handle 22 in its outermost position against` With the above described arrangement it will be seen that, when pressure is applied tothe buttcn-like member 2l, fthe flexible: reinforcing member 25 will be flexed outwardly with the screen and that, when the operating handle 22 is engagedothereby, the detent 3d will be moved downwardly so as to clear the abutment 35. As soon as the detent 34 clears the abutment 35, the out-swinging sash ll will be moved outwardly a slight distance and as a result the detent 3i will be prevented from again moving into locking engage ment with `the abutment 35. After the detent 34 has. been thus moved, the out-swinging sash YI'l may` be partially or fully opened by its operating mechanism l5.' It will be seen that the pressure exerted upon the operating handle 22, inv addition to rendering the locking means i8 inoperative, also functions to slightly displace the detent te .with-respect to the abutment 35 and render the locking means inoperative until the out-swinging sash l'l is again In Figure 9 of the drawings, the locking means is constructed in substantially the same manner as `has been disclosed by the showings made in Fig.

ures 8 and 10 of the. drawings. As here shown, thetwo out-swinging sashes it close upon a meet- `ing rail or dividing bar l2 which carries abutments 31 that cooperate` with detents 3i provided upon the locking means il, as is the case in the locking means i8 described above. In this showf ing, `the screen i3 is provided with disc-like memn bers 23 to indicate and locate the point at which pressure should be applied to engage the operating handles 2l. 'i

. In Figures 11, l2 and `13 of the drawings, there is shown an arrangement for a double sash window wherein two opposed out-swinging sashes 38 close upon a meeting rail or easement dividing ba'r ,39.i4 The sash locking means in this instance .comprises a pair of oppositely spaced supports Iii! having a horizontal shaft il disposed there beswingingvsashes 38. Because of the immovabley disposition of the locking means, it is necessary that the detents 44 be constructed so as to hook underthe abutments t5. Therefore, in order that the detents 44 may .operate tosnap into locking engagement with the abutments 135, the ends thereof are charnfered as at it. This arrangement requires that an initial opening movement be imparted to the out-swinging sashes 38. before the pressure upon the operating handles i3 can be released. This is in contradistinction to the Iarrangement described in connection with Figures 8, 9 and 10 of the drawings, wherein the lock .releasing pressure applied to the operating -hanor adjacentthe outside of the closed by its operL dies also functions to impart an initial opening a projection, as shown in dot and dash lines at 41 in Figure 12 of the drawings, may be formed on the outside of the operating handles 43. If such a projection is provided, it should be of a length suflicient to engage the adjacent outswinging sash 38 as soon as the detent 44 thereof has moved out of engagement with its cooperating abutment 45. It is also conceivable that this initial sash opening movement may be accomplished by providing an abutment engaging projection upon the detent 44, as illustrated by dot and dash lines at 48 in Figure 18 of the drawings. Such a projection 48 would exert an outward pressure upon the abutment 45 and move it and the out-swinging sash 38 suiliciently to clear the detent 44.

In view of the fact that the out-swinging sash locking means, described above, contemplates a coaction between a vertically stationary. abutment and a substantially vertically movable detent, it is necessary, because of the tendency of an out-swinging sash to sag, to provide a means between the stationary casement frame and the meeting edge of the sash which will properly position the sash with its locking detent or abutment in cooperation with the associated abutment or locking detent upon the casement. This can be accomplished in a number of ways. A preferred arrangement is to provide a horizontally disposed projection 49 upon the easement frame and a xture, upon the sash, having a horizontally disposed groove with which the projection 49 will cooperate. It is to be understood, however, that the position of the projection 4S and the groove 5E) may be reversed. The groove 5i? may be mounted upon the frame and the projection 49 may be provided upon the out-swinging sash.

In Figures i4 and 15 of the drawings, there is illustrated a modied form of the invention wherein an out-swinging sash 5l is shown as held in its closed position against a casement 52 by means of a spring 53 having a latching abutment 54 which overlaps the casement frame 52. The spring 53 is shown as secured upon the web o1' the out-swinging sash 5| and as projecting inwardly toward an overlying screen 55 where it is bent parallel therewith to form an operating handle 56, The operation of this embodiment of the invention is believed to be self evident and, therefore, a description of its' operation should be unnecessary.

While I have, for the sake of clearness and in order to disclose my invention so that the same can be readily understood, described and illustrated specic devic-es and arrangements, I desire to have it understood that this invention is not Vlimited to the specic means disclosed, but may be embodied in other ways that will suggest themselves, in View of this broad disclosure, to persons skilled in the art.
